To all whom 'it may concern:

Be it known that`I, GEORGE RosoN,l a citizen of the United States,residing at Murray, in the county of Hocking and State of Ohio, haveinvented certain new and useful Improvements in Pumps; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappert-ains to make anduse the same.

This invention relates to pumps, and more especially to those havingmultiple cylinders and reciprocating pistons therein; and the object ofthe same broadly speaking is to produce a pump for use in mines,etc.,having its parts as far as possible composed of woo-d and renderedseparable and removable by being held in place by metallic parts or mem*bers surrounding the wooden parts and detachably connected with eachother and mounted upon t-he b-ed.

It is well known that the water and other iuids in mines is frequentlymixed with powerful corrosives and other acids which soon destroy orrender useless the pumps employed for removing such water, if they aremade of metal. As wood successfully resists the action of thedeleterious substances, whether in its raw state or treated.

as with creosote or other preservatives, I have devised the improvedpump hereinafter described which is constructed with those partsadjacent the water made almost vision is made for readily getting at thevalves and other parts which wear rapildly` these objects areaccomplished by the construction hereinafter described and claimed andshown in t-he drawings wherein Figures 1 and 2 are respectively a planview and a. side elevation of the entire machine, these views and thissheet being the only instance wherein the power mechanism is illustratedand all remaining views being of the pump alone and on a larger scale;Fig. 3 is a side elevation of the pump with the sill in the .foregroundin section; Fig. 4 is a. rear end elevation of this pump; Fig. 5 is acent-ralY longitudinal section thereof, and Fig. 6 is a cross section onthe line' 6 6 of Fig. 5; Figs. 7 and 8 are respectively sections on thelines 7 7 and 8 8 of Fig. 5; Fig. 9 is a sectional detail on the line 99 of Fig. 7', looking toward the tended considerably to the rear forthat purpose. Between them extend cross bars 2 which carry longitudinalbeams, 8, all of .which may kconstitute a skeleton structure as shown inFig. 1 for supporting the journals 4 for the power shaft 5 carrying theVpower wheel 6 which is driven from a suitable source not necessary toillustrate. In

the present case this power sha-ft is gearedl as at 7 to a crank shaft 8mounted in suitable bearings 9, and this shaft is shown as having threecranks connected by pitmen 10 with cross heads 11 which move betweenguides 12 in a `manner well understood.

I have not considered it neessary to loose pulley on the power shaft 5;for the fact is that a mining pump of this character usually worksconstantly, sometimes at excessive speed as in cases wherethe minebecomes flooded, is always exposed to the weather, has little attentionpaid to it, and yet is one of the necessities in a mining propositionand often relied upon to save `lives and property. The deleteriouseffect of the chemicals present in the water pumped out of mines sooninjures and destroys the parts of pumps of this kind which are made ofiron and other metals, and I have there- `fore used wood so far aspossible; and as wood is liable to crack, warp, and surely to swell, Ihave reinforced or incased it as will, be described below.

The sills l are preferably of U-iron as best seen in section in Fig. 6,pierced with holes 15 y(shown in Fig. U2) for permittin access to thenuts or bolts within, and between said sills are disposed two like sidevplates 16 each having a wide flange 17 eX- tending throughout itslength, braced by illustrate the source of power for driving the wheel6, nor even to show a fast andy webs 18, and pierced with slots 19 forthe reception of bolts 2O by means of .which it is adjustably securedupon the upper flange of the sill 1. The side plate 16 also has anotherflange or outturned foot 21 extending along its lower edge throughoutits length, and possibly also braced by webs 22; and at its top it isprovided with lugs 23 which are spaced from each other so as to leave across channel between them as best seen in Fig. 3, for a purpose toappear.

The bed plate 25 has a flat upper surface which is narrower than thenormal distance between the inner surfaces of said side plates, and aseries of knuckles 26 along both edges dropped a little below the levelof said surface as best seen in Fig. 6 and provided with upright slots27 through which pass bolts 2S whereby the plate is suspended from thefeet 21 of the side plates 16. As seen in Fig. 3 similar knuckles 29 areformed beneath said feet 21 of the side plates and at proper intervalsto alternate with the knuckles 26, and these hanging knuckles areslotted as seen at 30 for the reception of horizontal bolts 31 whichpass through them and through a flange 32 extending along the edge ofthe bed plate proper and connecting all its knuckles 26. By this meansthere is therefore formed a trough comprising two upright sidesconsisting of the side plates 16 and a flat bottom consisting of the bedplate 25, the three members being connected by the interlockingknuckles, bolts, and slots so that they may be relatively adjusted for apurpose to appear below. The rear end of this soi-called trough (whichis the rear end of the pump proper and stands between its mechanism andthe power mechanism) consists of a rear end plate 35 best seen in Fig.4, having side ears 36 pierced with horizontal slots 37 through whichpass bolts 38 that. engage the webs 18 of the side plates 16. The plate35 also has a depending flange 39 with upright slots 40 through whichpass bolts 41 which engage a flange 42 depend ing from the rear end ofthe bed as best seen in Fig. 5. Thus it will be seen that the slots 30and 40 permit the Vertical adjustment of the bed plate, and the slots19, 27, and 37 permit the horizontal adjustment of the side plates, andtherefore the attachment of the rear plate in this manner does notprevent the adjustments above described. The nuts on the bolts 41 mayeasily be reached through the skeleton structure which supports thedriving mechanism first described above, and the holes 15 in the sills 1are obviously for the purpose of permitting access to the nuts of thebolts 31 and 28. The cap plate of this trough is in two members. Therearmost numbered 45 has an upright surrounding flange 46 connected bybolts 47 with the upper edge of the front plate and by other bolts 48with the lugs 23 of the sides. The front cap plate member 49 also has aflange 50 similarly connected by bolts 51 with the lugs 23, but saidflange across the rear edge of this plate depends beneath its otherwiseVflat lower surface into a. rib 52 which forms a feature of my inventionas will be eX- plainedl below. These two cap members partly close thetop of the trough-like structure above referred to but have a crosschannel between them for the outlet of my pump as will be explainedlater; and above said channel is disposed a top plate 55 which isremovably connected to the cap members 45 and 49 by hook-and-eyeconnections of any suit-able type such as the hook-bolts 56 whose nuts57 stand above the plate 55 and whose hooks engage eyes 58 in theflanges of said members. I might here say that the hook-and-eyeconnections hereinafter referred to may all be of this type or of anysuitable type without departing from the principle of my invention; andif it were not desired to remove the detachable members very frequentlythey could obviously be connected with the relatively fixed members andheld thereto by means of bolts if preferred.

So much of my structure as has thus far been described constitutes acasing which is by preference composed of metal, probably iron suitablytreated to prevent rust and corrosion as far as possible, and its partsare of the proper dimensions to contain the wooden elements hereinafterdescribed and from which is built up a pump of sullicient size andstrength to operate in connection with a mine.

Disposed within the metallic casing or housing described above are thepump barrels which in the present instance are three in number locatedside by side as best seen in Fig. 6,and as they are of like constructionI will describe but one. Each barrel consists of a wooden block 60 whichis right angular on all sides except that it is beveled off at its frontend as at 61 as best seen in Fig. 5, and throughout the length of thisblock it is provided with a cylindrical bore 62 forming the cylinder ofthe pump, the same being counterbored at 62a at its rear end. Thecylinder is intersected by the outlet port 63 bored from the top of theblock downward into the bore 62, and forward of such port by an opening64 which will stand directly above the inlet valve so that the lattermay be reached. Vithin said cylinder reciprocates the piston or plunger65 which in the present case is made of glass and molded around heads orenlargements 66 upon the pump rod 67, the latter extending out the rearend of the cylinder and being connected as by a screw thread 70 with thecross head 11. Bolted or screwed as at 69 to the rear plate 35 is theflange of a and through the bore of the stuiiing box.

yVihen three pump barrels are employed as in the present instance, thecranks of the shafts 8 will be set so that the severalpistons will movesuccessively rather than si-V multaneously within their cylinders, andin their reciprocation the pump rods 67 and the stuiiing boxes 68 (bothof which may be of metal) are protected from the action of the waterwithin the cylinder by the close fit of the packing around the piston orplunger. Between the blocks constituting the pump barrels 60, andbetween them and the various metal members and plates which surroundthem, I dispose sheets or strips of packing 71, as of rubber or thelike, the purpose being to permit the, swelling of the wooden blockswhen they become wet, and to permit their uneven swelling which I lindalmost invariably occurs, no matter what wood is selected nor howcarefully it is chosen. The use of a rather thick packing entirelyaround the block constituting the barrel is of advantage in connectionwith aglass piston to recpirocate within its bore, because if theoutward swelling of the wood is permitted there will not be so muchtendency of the wood to expand into its own bore and choke the latterupon the piston. l/Vhen absolutely necessary, the pump barrels may beremoved and replaced; but the pro-vision of removable stufling blocks 69permits the entire withdrawal ofthe piston rod and piston, and it willbe seen from the following description that all valves are accessiblefrom the exterior, and therefore it will not ordinarily be necessary todisarrange the pump barrel blocks when once they are locked in place.

Next forward of the set of barrels is disposed what I call the valveblock 75, best seen in Figs. 5 and 8, and the rear end of this block iscut off on a bevel 76 to match that of the frontend of the barrels 60,while a packing sheet 77 is interposed between the beveled faces. Theblock in the present instance is bored with three inlet ports 78registering with the bores 62 of the pump barrels which are purposelyenlarged as at 79 at their front ends just beneath the openings 64 so astogive the inlet valves free movement and to permit the operator to gainaccess thereto.

Next forward of the valve block 7 5 and upon the bed plate is disposedwhat I call the inlet block 80, the same being formed internally with aninlet chamber 81 extendlil) ing nearly throughout its length andcommunicating with all the inlet ports 78 as seen in Fig. 4, and themain inlet 82 communicates with this chamber. Between the blocks 8O and75 packing 77 may be interposed, vbut as the liquid within these blocksis not under pressure there is little likelihood o-f leakage and thesurrounding casing members are unnecessary. These blocks may be held inplace by any suitable means, but in the present instance Ihave shownupright yokes 83 extending across the face of the inlet block 80, andhook-andeye connections 84 between the lower ends of said yokes and thebed plate, and similar but longer connections 85 between the upper endsof said yokes and the front member 49 ofthe cap plate. It will beobvious that by disconnecting one or both of these Connections the inletblock and then the valve block may be removed so that access may be hadto the front end of the bore 62 in the various pump barrels 60; and asthe valve block is to carry the valves the latter come off with it andare readily accessible when it is removed. Here again the water from thetime it enters the main inlet 82 comes in contact only with wood andglass, and with whatever packing is employed, and in so far as possibleI avoid the use of metal in the formation of the. valves themselves. f

The inlet valves are disposed over the inner ends of the inlet ports 78and are of like construction, and I therefore need describe but one.This valve is by preference of the fiap variety, and its body consistsof a leather sheet of a size and shape sufficient to cover the port andto extend above the same where it is secured upon the inclined face 76of the valve block 75 by means of a stud bolt 91 of ber which passesthrough a-wooden washer 92, thence through the upper end of the sheet90, and into said block 75; and a fiber nut 93 engages the outer end ofsaid bolt, both of which with the washer stand within easy reach throughthe opening 64 as best seen in Fig. 5. Upon the free portion of saidrsheet of leather is disposed a glass weight 94, held thereon by a fiberpin passing through the weight and the sheet, and both` of theseelements are also accessible through the hole 64.

It will hardly be necessary to amplify the details of construction ofthe outlet valves 96,- as by preference they are precisely the sameexcepting only that each is disposed over the outlet port 63 in the topof a barrel 60 and open upward or awayfrom ythe bore 62 of the barrel,whereas the inlet valves open inward or into said bore. Atten tion isdirected, however, to the factthat the inlet valves are all mounted uponthe valve block 7 5, so that when the inlet block 80 is disconnected andwithdrawn the valve block and with it the valves can also be removedbodily, if the difficulty with the valves be such that it cannot becured by reaching through the openings 64. In order to permit access tothe latter, they are covered by removable hand-hold plates 97 held uponthe front cap plate 49 by bolts or screws 98 as best seen in Fig. 7.

The outlet chambei1 100 of this improved pump is made in the form of achannel extending throughout the length of a block 101 and opening outits bottom where it communicates with the outer ends of the ports 63 asbest seen in Fig. 5, the main outlet 102 being by preference through oneend of said block. The latter is separated from the top of the barrels60 by packing as described above, and packing may also be interposedbetween the top of this block and the bottom of the top plate 55, sothat when the hookand-'eye connections 56 between the top plate and themembers of the cap plate are drawn tight, the packing is compressed andthe outlet block is clamped close upon the top of the several pumpbarre-ls and incloses and surrounds the outlet valves 96. But as thewater within the outlet chamber 100 may be under some pressure,especially if the pipe from the main outlet 102 be led up hill, Ipreferably dispose end plates 105 at both ends of this block and connectthem along its sides by bolts 106 passing inside the hook-and-eyeconnections 56 so as to form a metallic frame entirely surrounding thisblock and preventing it from bursting and splitting. The top plate 55will by preference be provided with openings 104 disposed above andnearly if not quite in alinement with the outlet ports 63 and closed byhandhold plugs or plates 103 (see Fig. 1) secured to said top plate bybolts or screws 106, and when the latter are removed and the plugswithdrawn access may be had to the interior of the outlet chamber 100and to the outlet valves 96 therein if they need attention. If, however,serious difliculty is encountered with them, t-he top plate can beunhooked from the members of the cap plate and removed, and then theentire block 101 can be lifted olf to expose all the valves which canthereafter be readily repaired or replaced if necessary.

In setting up the various parts of this improved pump, the sills willdoubtless be mounted on a stone foundation and the installation of thedriving mechanism will need no explanation. The two sides having beenbolted to the bed plate in the form of a. trough, the whole is slippedinto the front ends of the sill and connected to the upper kflanges o-fthe latter by the bolts 20; then the pump barrels are put in place withthe appropriate packing and the connections between the sides and bedadjusted to hold the blocks 60 comprising said barrels very tightly inplace with the grooves 152 across their upper faces in strict alinementfor a purpose to appear; then the rear plate is applied and bolted inplace; then the two members of the cap are put into place and bolted tothe front and side plates as has been described, the rib 52 of the frontcap plate 49 entering the alined grooves 152 of the barrels 60; then thevalve block with its valves and packing is brought into position as seenin Fig. 5, and forward of it the inlet block 80 with the packing betweenthe two blocks; then the outlet block 101 is placed over the outletvalves and the top plate 55 applied to it with the interposed packing.When the bolts 47 are drawn up tight the entire cap plate is connectedwith the rear plate around the channel in which the outlet block 101 issituated, and the engagement of the rib 52 with the grooves 152 holdsthe barrel blocks 60 against said rear plate and in correct position;and if now the yokes 83 and the hook-and-eye connections 84 and 85 areapplied and tightened up, all parts will be clamped securely in position longitudinally of the structure and itremains only to apply thetop plate 55 over the outlet block and tighten up its hookand-eyeconnections to complete the work. Thereafter the rotation of the crankshaftwill cause the successive reciprocation of the pistons within thecylinders and at the rear stro-ke of each piston water is drawn inthrough the inlet port, under the inlet valve which rises against itsweight, while at the forward stroke of t-he piston the inlet valvecloses by its weight and the water drawn y into the cylinder is ejectedupward through the outlet port 63, its valve 96 opening against itsweight. Thus there is a steady flow of water from the main inlet 82through the inlet chamber and one of the inlet ports and pump, to andthrough one of the outlet ports and the outlet, chamber and main outlet;and throughout the entire course the water has not come into contactwith any met-al. What may leak around the pistons may gain access to thepiston rods which I have stated are by preference made of soft steel,but if so they may be readily replaced whenever they become corroded, orif possible some other material may be substituted for the steel.
